RMS Niagara was an ocean liner launched on 17 August 1912 and owned by the Union Steam Ship Company. She was nicknamed "the Titanic of the Pacific", but after the sinking of the real RMS Titanic this was dropped in favour of "Queen of the Pacific". (RMS Niagara was also the name of an ocean liner built in 1848 for the Cunard Line.) At the start of World War II, RMS Niagara was operated by the Canadian-Australasian Line, maintaining a service from Auckland, New Zealand, to Suva and Vancouver.
